#70# watts

Power is found through the equation,

#P=W/t#

#W# is the work done in joules

#t# is the time taken in seconds

Work done is given by the equation,

#W=F*d#

#F# is the force exerted in newtons

#d# is the distance moved in meters

And so, the work done is:

#W=35 \ "N"*10 \ "m"#

#=350 \ "J"#

Therefore, the power used up is:

#P=(350 \ "J")/(5 \ "s")#

#=70 \ "W"#
